Предметно-ориентированное проектирование в микросервисной архитектуре

С увеличением сложности разработки программного обеспечения для решения современных бизнес-задач необходимы такие подходы, как предметно-ориентированное проектирование (Domain-Driven Design, DDD). DDD уже используется в различных программных проектах с разными архитектурными стилями. Хотя в некоторых исследованиях изучалось разложение бизнес-доменов или унаследованных монолитных систем на микросервисы, пока отсутствует конкретная информация относительно практической реализации DDD в этом архитектурном стиле. Для повышения ясности в отношении использования DDD в разработке систем на основе микросервисов в нашей статье систематизированы выводы о целях использования DDD, его моделях, связанных технологиях и методах. Нами был проведен систематический обзор литературы из 35 статей. Тематический анализ помог выявить 11 тем и пять тем более высокого порядка. Основываясь на проделанном анализе, мы пришли к выводу, что идентификация микросервисов становится основной мотивацией принятия разработчиками DDD, но при этом вовсе не является единственной причиной использования DDD, о которой сообщается в литературе. Наконец, наш анализ выявил преимущества и проблемы в использовании DDD в архитектуре микросервисов, которые будут учитываться при проведении работ в будущем.
